Annotation: New research into general psychiatric services for adults with intellectual disability and mental illness

Background   There are a variety of models for the mental health care of adults with comorbid intellectual disability (ID) and mental illness. There has been a long-running debate as to whether this should be provided by general psychiatric or specialised ID services. A previous review concluded that there was no clear evidence to support either model with research being often of a poor quality, lacking replication, and outcome measures were often inappropriate or varied between studies. This review aims assess differences in outcome for patients with ID and mental disorders treated in general or specialised ID mental health services.
Method   A literature review was conducted using electronic databases and websites of ID and mental health organisations to locate all references where people with ID receive mental health care in general psychiatric services from 2003. No meta-analysis was attempted because of the divergent nature of the studies.
Results   People with ID (especially severe ID) have reduced access to general psychiatric services. General psychiatric inpatient care is unpopular especially with carers but can be improved by providing specially trained staff and in-reach from community ID teams. Opportunities may exist to enhance the care of people with borderline intellectual functioning within general psychiatric services.
Conclusions   Although no new randomised controlled trials have been published, the weight of research is accumulating to suggest that provision of general psychiatric services without extra help is not sufficient to meet the needs of people with ID.     

Predictors of violent behavior among acute psychiatric patients: clinical study

Aim:  Violence risk prediction is a priority issue for clinicians working with mentally disordered offenders . The aim of the present study was to determine violence risk factors in acute psychiatric inpatients.
Methods:  The study was conducted in a locked, short-term psychiatric inpatient unit and involved 374 patients consecutively admitted in a 1-year period. Sociodemographic and clinical data were obtained through a review of the medical records and patient interviews. Psychiatric symptoms at admission were assessed using the Brief Psychiatric Rating Scale (BPRS). Psychiatric diagnosis was formulated using the Structured Clinical Interview for DSM-IV. Past aggressive behavior was evaluated by interviewing patients, caregivers or other collateral informants. Aggressive behaviors in the ward were assessed using the Overt Aggression Scale. Patients who perpetrated verbal and against-object aggression or physical aggression in the month before admission were compared to non-aggressive patients, moreover, aggressive behavior during hospitalization and persistence of physical violence after admission were evaluated.
Results:  Violent behavior in the month before admission was associated with male sex, substance abuse and positive symptoms. The most significant risk factor for physical violence was a past history of physically aggressive behavior. The persistent physical assaultiveness before and during hospitalization was related to higher BPRS total scores and to more severe thought disturbances. Higher levels of hostility–suspiciousness BPRS scores predicted a change for the worse in violent behavior, from verbal to physical.
Conclusion:  A comprehensive evaluation of the history of past aggressive behavior and psychopathological variables has important implications for the prediction of violence in psychiatric settings.     

Characteristics of people with intellectual disability admitted for psychiatric inpatient treatment

The present prospective study describes the demographic, medical and psychosocial characteristics of 40 people with intellectual disability who were referred for psychiatric inpatient treatment in the special psychiatric unit of the Special Welfare District of South-west Finland. Three different control groups were used to study: (1) demographic variables (n = 122); (2) medical history (n = 39); and (3) psychosocial factors (n = 20). The symptoms leading to an admission to inpatient care and the connections of these clinical signs with the discharge diagnosis were evaluated. The typical inpatients were young males with mild intellectual disability, psychosis and a previous psychiatric diagnosis. They had lived in several places during their lives and their economic situation was poor. Affective and/or disruptive symptoms were the most common causes of an admission to inpatient care. The largest diagnostic group at discharge consisted of patients with psychotic disorders. The people with intellectual disability who were admitted for inpatient care formed a subgroup with certain psychiatric symptoms and social problems. Specialist psychiatric expertise is absolutely necessary for the treatment of this subgroup.     

Open wards versus locked wards of general hospitals in the treatment of psychiatric patients with medical comorbidities: A cross-sectional study in Tokyo

Aim:  Treatment of medical comorbidities among psychiatric patients is an expected role of general hospital psychiatric wards. The purpose of this study was to clarify whether locked wards of general hospitals are necessary in the treatment of psychiatric patients with severe medical comorbidities.
Methods:  A cross-sectional study concerning patients who required admission due to both somatic and psychiatric diseases was performed all over Tokyo during a 2-month period. Demographic and clinical characteristics of patients who were admitted to locked wards of general hospitals were compared with those of patients admitted to open wards of general hospitals.
Results:  In locked wards, the rate of organic mental disorders, median Lack of Judgment and Insight from the Positive and Negative Syndrome Scale, and rate of diseases requiring surgery were significantly higher than those in open wards. The rate of patients with medical comorbidities who could not be admitted was significantly higher for open wards than for locked wards. Furthermore, the rate of patients with both medical comorbidities and attempted suicide who could not be admitted was significantly higher for open wards than for locked wards.
Conclusion:  Locked wards may be necessary to treat severe psychiatric patients with severe medical comorbidities.     

Prevalence and identification of alcohol use disorders among severe mental illness inpatients in Taiwan

Aims:  A higher prevalence of alcohol use disorders (AUD) among psychiatric patients has been reported previously and the identification rate is relatively low. This study was designed to investigate the prevalence and identification of AUD among acute psychiatric inpatients with severe mental illness in a psychiatric hospital in Taiwan.
Methods:  In a two-phase case identification strategy, the Alcohol Use Disorders Identification Test (AUDIT) was used as the first phase screening tool and the Structured Clinical Interview for DSM-IV-TR as the second phase diagnostic interview. The definition of identification was diagnosis of AUD on medical record at discharge.
Results:  Of 400 respondents, 42 screened positive and 358 screened negative. All screen-positive respondents and 35 screen-negative respondents entered the second phase interview. The weighted lifetime prevalence of alcohol dependence was 8.3% (95% confidence interval [CI]: 4.6–11.9%); alcohol abuse, 1.5% (95%CI: 0.2–2.8%); and AUD, 9.8% (95%CI: 5.7–13.8%). The overall identification rate of AUD by medical staff was 28.2% (0% for alcohol abuse and 33.3% for alcohol dependence). Patients with mood disorders were prone to being undetected as having AUD.
Conclusion:  AUD comorbidity was common among inpatients with severe mental illness in Taiwan and was easily neglected by medical staff. It is necessary to use a validated screening questionnaire, such as AUDIT, to detect high-risk patients and then give appropriate interventions to enhance treatment outcome.     

Psychiatric diagnoses in relation to severity of intellectual disability and challenging behaviors: a register study among older people

ABSTRACT

Objective: To investigate the possible association between severity of intellectual disability (ID) and presence of challenging behavior, respectively, on diagnoses of psychiatric disorders among older people with ID.

Methods: People with a diagnosis of ID in inpatient or specialist outpatient care in 2002–2012 were identified (n = 2147; 611 with mild ID, 285 with moderate ID, 255 with severe or profound ID, and 996 with other/unspecified ID). Moreover, using impairment of behavior as a proxy for challenging behavior, 627 people with, and 1514 without such behavior were identified.

Results: Severe/profound ID was associated with lower odds of diagnoses of psychotic, affective, and anxiety disorders than was mild/moderate ID. People with moderate ID had higher odds than those with mild ID of having diagnoses of affective disorders. Diagnoses of psychotic, affective, and anxiety disorders, and dementia were more common among people with challenging behavior than among those without.

Conclusions: People with severe/profound ID had lower odds of receiving psychiatric diagnoses than those with mild and moderate ID. Whether this is a result of differences in prevalence of disorders or diagnostic difficulties is unknown. Further, challenging behaviors were associated with diagnoses of psychiatric disorders. However, the nature of this association remains unclear.     

Procedural discourse in intellectual disability and dual diagnosis

Background   Knowledge of discourse abilities of adults with intellectual disability (ID) and mental illness is limited. The present study examined the procedural discourse skills of two cohorts of adults with ID – one cohort with ( n  = 7) and one cohort without ( n  = 7) a psychiatric diagnosis of psychosis.
Methods   Participants completed the 'dice game', a procedural discourse elicitation procedure that has been used by previous researchers.
Results   Results revealed that while all participants demonstrated an understanding of the task, participants with ID alone were more able to communicate the key elements of the game than the participants in the dual diagnosis group.
Conclusions   Results of this investigation suggest that individuals with dual diagnosis have difficulties that may relate to previously identified discourse impairments in people with schizophrenia, and this may relate to a larger difficulty in taking into account the listener's needs.     

A validity study of the Working Group's Orientation Test for individuals with moderate to severe intellectual disability

Background   Decline in orientation skill has been reported as an early indicator of Dementia of Alzheimer's Type (DAT). Orientation subtest of the Working Group's Test Battery was examined whether this test is useful to identify DAT patients among adults with moderate to severe ID.
Methods   Sixteen DAT patients and 35 non-demented normal controls with moderate to severe ID were followed for a year using Orientation Test. The scores on the baseline evaluation and the longitudinal changes over a 1-year period among the DAT patients and the normal controls were compared. The effects of age and etiologies of ID on the performance of Orientation were also examined.
Results   The DAT group's score was significantly poorer than that of the normal control group on the baseline evaluation. The score changes over the 1-year period were not significantly different between the groups. However, there was a considerable overlap between the score distributions of the two groups. The effects of age and etiologies of ID on the performance of Orientation were not significant.
Conclusions   Screening DAT patients based only on the score of the Orientation Test of the Working Group's Test Battery may produce a large number of diagnostic errors.     

Falls in a Psychiatric Institution in Beijing, China

PURPOSE.  This study aimed to determine the rate of falls and their relationship with sociodemographic and clinical factors in a psychiatric institution in Beijing, China.
DESIGN AND METHODS.  The case notes of 7,921 inpatients were scrutinized to identify patients who fell while in the hospital.
FINDINGS.  The fall rate in this study was 1.2% of all inpatients. Nearly all (89.7%) falls occurred when patients attempted to stand up, get out of bed, or walk.
PRACTICE IMPLICATIONS.  Effective measures should be provided to prevent falls in psychiatric wards. A prospective study exploring predictors of falls is warranted.     

Ethnic variation in service utilisation among children with intellectual disability

Background   This study examined whether service utilisation among children with intellectual disability (ID) varied by ethnic cultural group.
Method   Survey carried out in four special schools in London. Information was provided by school teachers using case files, and 242 children aged 7 to 17 years with mild and moderate ID were identified. Ethnic categories were derived from self-reported main categories. Service utilisation categorised as use of: child and adolescent mental health services (CAMHS), social services, physical health and education services.
Results   Child and adolescent mental health services uptake was lower for South Asians than for White British ( P  = 0.0487). There were statistically significant differences among ethnic groups for community-based social services uptake (being the highest for the Black groups and the lowest for South Asians, P  = 0.015) and respite care uptake (being the highest for the Black and White European groups and the lowest for South Asians, P  = 0.009). In regression analysis family structure predicted CAMHS service utilisation and social service community support. Ethnicity predicted use of respite care.
Conclusions   Significant ethnic differences in service utilisation among children with ID were found for both CAMHS and social service contact. There was particularly low service use for the South Asian group. These differences might arise because of differences in family organisation, as more South Asian children lived in two-parent families, which may have been better able to provide care than single-parent families. Other factors such as variation in parental belief systems and variation in psychopathology may be relevant. Implications are discussed.     

Does visual impairment lead to additional disability in adults with intellectual disabilities?

Background   This study addresses the question to what extent visual impairment leads to additional disability in adults with intellectual disabilities (ID).
Method   In a multi-centre cross-sectional study of 269 adults with mild to profound ID, social and behavioural functioning was assessed with observant-based questionnaires, prior to expert assessment of visual function. With linear regression analysis the percentage of variance, explained by levels of visual function, was calculated for the total population and per ID level.
Results   A total of 107/269 participants were visually impaired or blind (WHO criteria). On top of the decrease by ID visual impairment significantly decreased daily living skills, communication & language, recognition/communication. Visual impairment did not cause more self-absorbed and withdrawn behaviour or anxiety. Peculiar looking habits correlated with visual impairment and not with ID. In the groups with moderate and severe ID this effect seems stronger than in the group with profound ID.
Conclusion   Although ID alone impairs daily functioning, visual impairment diminishes the daily functioning even more. Timely detection and treatment or rehabilitation of visual impairment may positively influence daily functioning, language development, initiative and persistence, social skills, communication skills and insecure movement.     

Psychiatric inpatient care for adults with intellectual disabilities: generic or specialist units?

BACKGROUND: When adults with intellectual disabilities (ID) require a psychiatric admission, general adult mental health units are often used. Specialist units have emerged recently as a care option but there is only limited evidence of their effectiveness. Thus this study aims to describe and evaluate the effectiveness of a specialist inpatient unit and report on the utilization of generic and specialist inpatient services. METHOD: All patients admitted to a specialist ID psychiatric unit were evaluated on admission and immediately after discharge on a number of outcome measures. In addition, they were compared with those admitted to general adult mental health units covering the same catchment area. RESULTS: Significant improvements were demonstrated within the specialist unit cohort on measures including psychopathology, global level of functioning, behavioural impairment and severity of mental illness. The specialist unit patients had a longer length of inpatient stay but were less likely to be discharged to out-of-area residential placement. CONCLUSIONS: Specialist units are an effective care option for this group of people.     

Association between feasibility of discharge, clinical state, and patient attitude among inpatients with schizophrenia in Japan

Aim:  There have been some studies on the feasibility of discharging mentally ill inpatients from mental hospitals. The purpose of the present study was to investigate how a psychiatrist judges whether an inpatient can be discharged.
Methods:  A survey regarding such judgments on discharge was conducted involving 549 inpatients with schizophrenia with a hospital stay of ≥1 year. Relationships between psychiatrist judgments on discharge and the Brief Psychiatric Rating Scale (BPRS), Scales for the Assessment of Negative Symptoms (SANS), Global Assessment Scale (GAS), patient attitude to discharge, and other variables were investigated. A similar analysis was conducted regarding patient attitudes toward discharge.
Results:  After controlling for potential confounding factors using multiple logistic regression, the judgments showed significant relationships with BPRS-P, SANS, GAS, and age. Patient attitudes showed significant relationships with the length of the current hospital stay, SANS, and psychiatrists' judgments.
Conclusion:  A psychiatrist's judgment regarding discharge is a comprehensive decision that takes into account psychiatric symptoms, social functioning, and age. Such a judgment could also affect a patient's own attitude toward discharge.     

Forensic psychiatric perspective on criminality associated with intellectual disability: a nationwide register-based study

Background   Contrasting views exist over the association of intellectual disability (ID) and criminal offending. This nationwide study attempts to shed further light to expand understanding to substantiate the relation between socio-demographic characteristics, psychiatric co-morbidity and criminal behaviour among the Finnish forensic population with ID.
Method   We reviewed all forensic psychiatric examination reports of individuals with ID who underwent a pre-trial forensic psychiatric evaluation in Finland during an 11-year period (1996–2006).
Results   One-third of the offenders had been regularly and sufficiently treated as outpatients. Half of the offenders had previous criminality, and the single most common crime was arson. Almost half of the offenders were diagnosed with alcohol abuse/dependence and two-thirds with any substance abuse/dependence. Furthermore, almost half were intoxicated during the index crime. Antisocial personality disorder was diagnosed in 25% of the offenders. Almost half of the offenders were placed in involuntary special care for the ID, which lasted ca 2 years. Among the last-mentioned, two-thirds of the nursing care plans lacked recommended structure.
Conclusions   The offenders with so-called triple diagnosis – substance abuse, mental illness and ID – form a small subgroup of criminal offenders with complex needs. The results of the present study underline the importance of close, long-term cooperation among specialists in the field of ID, addiction service, mental health services and forensic psychiatry.     

General psychiatric services for adults with intellectual disability and mental illness

BACKGROUND: Adults with intellectual disability (ID) and mental illness may use general or specialist psychiatric services. This review aims to assess if there is evidence for a difference in outcome between them. METHODS: A literature review was conducted using a variety of electronic databases and hand-search strategies to identify all studies evaluating the outcome of people with ID and mental illness using general psychiatric services. RESULTS: There is no conclusive evidence to favour the use of general or specialist psychiatric services. People with ID stay less time on general psychiatric than specialist inpatient units. People with severe ID appear not to be well served in general services. Older studies of inpatient samples suggest a worse outcome for people with ID. Novel specialist services generally improve upon pre-existing general services. Assertive outreach in general services may preferentially benefit those with ID. Recent studies suggest similar lengths of stay in general psychiatric beds for people with and without ID. CONCLUSIONS: Although 27 studies were located, only two were randomized controlled trials. The evidence is poor quality therefore further evaluation of services employing a variety of designs need to be employed to give more robust evidence as to which services are preferred.     

The impact of the organisation of mental health services on the quality of assessment provided to older patients with depression

OBJECTIVE: The objective of this study was to examine the impact of the organisation of mental health services on the quality of medical and psychiatric assessment provided to patients with depression over 50 years of age. METHOD: A retrospective clinical audit of 99 patients with primary depressive disorders who were over 50 years of age was used. These patients were assessed initially by specialised psychogeriatric outpatient and community services (44%), community-based adult mental health services (35%) or an inpatient service (21%). At 2-3 years follow up, clinical outcomes were rated by treating physicians and included current depression status, cognitive and medical status, course of illness since initial assessment and current living circumstances. RESULTS: Patients who were assessed by the community-based adult mental health service received the least comprehensive assessment. Although these patients were more likely to be living independently, they tended to have the poorest depression outcome. Patients who were assessed by the specialised or inpatient services received more comprehensive initial assessment and better coordinated long-term care. Although these patients had more medical and cognitive comorbidity they had better overall depression outcomes. CONCLUSIONS: Within a service system that determines access according to an arbitrary age of onset, patients with depression receive the best assessment from specialised psychogeriatric services. However, patients with an early age of onset, more chronic disorders and poor outcomes are treated largely within community-based adult services. Psychiatric services need to ensure that all older patients with depression receive appropriate biomedical and psychosocial assessment, as well as continuity of medical and psychological treatment.     

The development of a new measure for the assessment of psychopathology in adults with intellectual disability

Background   People with intellectual disability (ID) and untreated psychiatric disorder lead unnecessarily difficult and unhappy lives. The prevalence of mental illness in children and adults with ID is greater than that found in the general population. A carer-completed checklist of psychopathology that could be used with both children and adults would help identify those individuals with ID most likely to have a mental health problem, help ensure that they receive the limited services that are usually available and also assist the process of clinical assessment, diagnosis and management.
Method   This research aimed to develop a reliable and valid carer-completed checklist of psychopathology for adults with ID by redeveloping an existing measure for children with ID, the Developmental Behaviour Checklist (DBC-P). The new checklist, The Developmental Behaviour Checklist for Adults (DBC-A) was devised by changing, deleting and adding to DBC-P items. Reliability studies were conducted with paid and family carers, and DBC-A scores were compared with the results from two other measures of psychopathology.
Results   One DBC-P item was deleted, seven items changed and 12 items added. The psychometric properties of this new checklist, the DBC for Adults with ID (DBC-A), were investigated and found to be satisfactory. Intraclass correlations for test-retest and inter-rater reliability ranged from 0.72 to 0.85, and concurrent validity with two measures of emotional and behavioural disturbance was satisfactory.
Conclusions   The carer-completed DBC-A provides a broad and comprehensive survey of the emotional and behavioural problems of adults with ID. It has satisfactory psychometric properties and therefore can be used with confidence in clinical, research and service settings, and its development allows continuous assessment of psychopathology across the lifespan for all people with ID.     

Clinical characteristics of inpatient adolescents with severe obsessive-compulsive disorder

Obsessive-compulsive disorder (OCD) is a common disorder in adolescents, usually treated in the outpatient setting. Our aim in this study was to evaluate the clinical characteristics of adolescents with severe OCD that required hospitalization. A total of 342 patients consecutively admitted to a psychiatric adolescent inpatient unit and 87 healthy volunteers were assessed by a semistructured interview for clinical diagnosis, suicide risk factors, aggression, ego defense mechanisms, and intelligence. Patients with OCD (n=40) were compared to other four diagnostic patient groups with psychotic, affective, conduct, and eating disorders, as well as to normal controls. Adolescent inpatients with OCD experienced less separation anxiety than all the other psychiatric groups (P < .01) and were less impulsive than controls (P < .001). They differed in aggressive/impulsive traits and hospital-related behaviors from other diagnostic groups. Adolescent inpatients with OCD consist of a unique subgroup in the inpatient unit in terms of their clinical characteristics and risk factors for suicide. These characteristics should be taken into account when developing a treatment plan for these difficult-to-treat inpatients.
